£499 sounds too much for a VW service plan. The standard VW service plan for cars under 1 year old currently costs £296.82 as an up front payment, or the cost can be spread over 18 months (monthly payment of 16.49). It covers the first two services. VW often run a promotion on the service plan for customers PCP’ing with VWFS; they’re currently offering the two year service plan for £199 for PCP customers. If you have a service plan, you should have some form of document outlining what it includes, and if you pay monthly, you receive a monthly invoice from VWFS. Could you have possibly bought a dealers own equivalent of VW’s service plan that might cover, say, the first three services - hence the higher price than VW’s price for their standard two service offering.
The ‘tlc’ (package) that you were sold sounds more likely to be one of some those overpriced ‘extras’ that the dealer makes a healthy profit on (e.g. paint work protection, alloy wheel and tyre insurance, scratch and ding insurance). When I bought my last car, the dealer tried to sneak Lifeshine paintwork protection into the deal for some stupid price without telling me - cant remember the exact price, but it was somewhere between £300-£400 pounds. I politely told them where they could stick their Lifeshine paintwork protection!
